A recent study from Harvard University has identified a potential connection between eating eggs and the risk of developing certain types of cancer, particularly breast, ovarian, and fatal prostate cancer.
The findings, published in the British Journal of Nutrition, shed light on the role egg consumption might play in the development of cancers related to sex hormones.
The study, led by researcher N. Keum and colleagues, analyzed data from multiple studies through a dose-response meta-analysis.
This method allowed the team to examine how different levels of egg consumption might influence the risk of breast, prostate, and gynecological cancers. Their results suggest that eating more eggs could be linked to an increased risk of some cancers.
For breast cancer, the study found a significant association between consuming five or more eggs per week and a higher risk compared to those who do not eat eggs at all.
Similarly, for ovarian cancer and fatal prostate cancer, consuming five eggs per week was also associated with an increased risk. However, no link was found between egg consumption and the overall risk of developing prostate cancer, only for the fatal form.
The researchers noted that while their findings indicate a modestly elevated risk, the results do not definitively prove that eating eggs causes cancer.
They highlight the importance of further studies to understand the mechanisms behind these associations and to determine if other factors might contribute to the observed risks.
Eggs are a common food in many diets and are valued for their nutritional benefits, including high-quality protein and essential nutrients. However, they also contain cholesterol and certain compounds that may influence hormone levels or cancer-related pathways.
Previous research has suggested a possible link between egg intake and cancers influenced by sex hormones, but the exact relationship remains unclear.
The study adds to ongoing discussions about the potential risks and benefits of egg consumption.
While eggs can be part of a balanced diet, moderation and consideration of individual health risks may be important, especially for people concerned about hormone-related cancers.
Understanding how lifestyle and dietary choices affect cancer risk is an important part of cancer prevention efforts.
This study encourages further exploration into the complex relationship between diet and cancer, aiming to help individuals make informed decisions about their health.
